Opinion: Depends on the exact model of powerbook, but I give you 50%-50% of it working.
This is Crucial's generic laptop RAM. It's fine thing, but it is not guaranteed to work on Powerbooks. Crucial's Powerbook RAM is a special build CT12864X335AP or CT12864X335.16 NewEgg of course makes no guarantee of compatibility. (you did see the review from the purchaser who tried 2 of these without success in their 17" powerbook, right?)
I recommend that you stick with a reputable vendor who tests and guarantees compatibility with your model Powerbook, has a lifetime warranty, and a no-cost return if it doesn't work.
If that Crucial doesn't work, you'll be out time, trouble and shipping costs. Wost case, you may get stuck with a restocking charge depending on seller policies.
In the USA I like
Data Memory Systems
